Stenus perrarus View in CoL nov.sp. ( Figs 39 View Figs 30-41 , 64 View Figs 55-69 )
Type material: Holotype () and 3 - paratypes: Taiwan: Taoyuan Hsien: Takuanshan Forest , 1650m, 17.IV.1990, A. Smetana (T 5). Paratypes: 2, 1: Taipeh Hsien: Fushan , 27.IV.1999, H. Sugaya.- HT and PTT in coll. Smetana (Ottawa), PTT also in cN and in cP.
Description: About as in S. perturbator nov.sp.
Length: 2.5-3.1mm (forebody: 1.3-1.4mm).
PM of the HT: HW: 28.8; DE: 15; PW: 21.5; PL: 23.5; EW: 27.8; EL: 23; SL: 16.
Male: Ventral characters as in S. persimplex nov.sp., but the apical emargination of sternite 8 less deep and broader (LS: ED= 51:3). Aedeagus (fig. 39), apical portion of median lobe very short, convexely narrowed, apex narrowly rounded, expulsion hooks not contiguous medially; parameres much longer than median lobe, with 9-10 apical setae.
Female: Sternite 8 at posterior margin obtusely angled triangular, apex nearly acute. Valvifer as in S. perturbator . Spermatheca (fig. 64), infundibulum at least 3x as long as broad.
In many respects very similar to S. persubtilis , but the median portion of frons less elevated, the elytral punctation slightly coarser, the abdominal punctation slightly less dense, interstices on last tergites distinctly larger than punctures.
Comparative notes: This new species resembles extremely S. persimplex nov.sp., but the head is slightly less broad, the sexual characters are different. For identification see key.
Etymology: Since I only saw few specimens I name this new species " perrarus " (Lat.= very rare).
